I welcome you, dear colleagues! Today I want to talk to you about the type of lamps used in aquariums to illuminate our underwater gardens and its inhabitants.
It is very important to choose normal lamps for lighting a decorative aquarium, as this will directly affect the intensity of illumination and the correctness of the spectrum, and these two parameters are closely intertwined.
These lamps are a universal light source, equipped with a screw base with tungsten filament. These also include halogen lamps.
Although halogens are not used in aquarium lights, it can still be installed there. Sometimes incandescent bulbs are used to light not large pools with fish.
However, the color spectrum of such lamps is very poor (no more than 2700K) due to its proximity to the red spectrum, so this type of lamps is not in widespread demand in aquarism.
When adding incandescent bulbs to the luminaire, you need to take into account the fact that such a spectrum of light emission will provoke the rapid development of green algae about which I have already written on the blog, so now I will not dwell on this issue in detail. Better yet, you limit yourself to the use of these lamps because they emit a lot of heat energy and suck a lot of electricity.
Better light bulbs illuminate aquaterrariums and terrariums with eared turtles.
Lamps of this type and fluorescent lighting make them the most popular. Thanks to luminescent lamps you can light a large area of the aquarium.
A huge advantage of such lamps is that there are so many varieties of them and they are easily accessible. Luminescent lamps are available in stores in a very wide color range. They also differ in diameter: T5, T8, T12 – 16mm, 26mm and 38mm respectively.
Lamps of types T12 and T8 are considered the most optimal and are used in ordinary aquarium lamps. If you have a deep enough aquarium (more than 50 centimeters), there are lamps that give a higher light output.
They are referred to as VHO (Very High Output) and HO (High Output).

Gas discharge discharge lamps are used to illuminate aquarium reefs. They have a unique and very valuable feature – the creation of the effect of “sparkling light.” This effect is similar to sunlight like shallow reefs inhabited by mollusks, corals and sea anemones.
For metal halide lamps need special lamps and ballasts, as they are very powerful. Their power ranges from 70 to 1000 watts.
Any power needs a compatible ballast. Another feature of this type of lamp: they spread the light pointwise. That is, the entire thermal spectrum of light will be concentrated in one place, and this is very good.
Since these lamps are warm enough, they need to be cut down from time to time for an hour to relax. Try not to touch the flask with your hands, since light transmission by the flask glass is disturbed.
Due to the strong heating, metal halide lamps are additionally equipped with a fan to cool the lamp and place the entire structure at some distance from the surface of the water in order to prevent the aquarium from overheating.
